You will need to add 100 to the hundreds column. 400 + 100 = 500 560 Consider the number of tens when answering this question. 629 has 62 tens. 62 tens - 6 tens = 56 tens Remember to include the ones in your answer. 569

20 x 4 = 80 or 4 x 4 = 16 2 4 80 + 16 = 96 1 4 9 6 24 Remember to only add the numerator. The denominator stays the same. 10 12

Remember to only subtract the numerator. The denominator stays the same. 2 5 1 7 8 4 + 2 7 7 3 5 4 5 7 4557 1 1

2 . 8 0 . 6 + . 3 4 3.4 1 The digits move one place to the th th right when dividing by 10. A good T O t h way to remember is 10 has one 3 8 zero so one place is moved. 3.8 8 3

÷ 48 8 = 6 6 x 3 = 18 18 8 2 9 3 4 + 4 1 5 5 9 8 8 7 0 87,089 1

Use your number bonds to 1000 to find the answer. 1000 - 900 = 100 39,100 1 1 2 1 8 1 8 6 9 3 2 5 - 3 6 8 3 7 2 3 4 8 8 8 832,488

This symbol means 'squared'. To find the answer, you must multiply 12 by itself. 12 x 12 = 144 144 We can use our known facts to 9 x 6 = 54 help us to answer this question. 90 x 6 = 540 900 x 6 = 5400 5440

We can use our known facts to help us to answer this question. ÷ 300 5 = 60 Remember to replace the zero to 50 5 = 10 ÷ give a final answer. ÷ 350 5 = 70 700 The digits move one place to the left when multiplying by 10. A good th th H T h way to remember is 10 has one t zero so one place is moved. 3 7 0 7.03 3 7 0

12 3 x 4 6 7 2 9 + 12 12 3 x 4 3 15 or 1 12 8 7 = + 12 12 12 Steps to success Find the lowest common denominator. Convert both fractions. In this case 7 will remain the same. 12 Remember, when converting, whatever has been done to the denominator, must be done to the numerator. Calculate

10 2 x 5 4 9 1 - 6 10 2 x 5 9 5 8 4 = - 10 10 10 10 Steps to success Convert the whole number into a 7 5 improper fraction. x Calculate 1 8 Convert into a mixed number. 3 35 Remember, sometimes this will be a or 4 8 whole number only. 8

Don't forget to use a place holder zero. Always line up your columns 3 . 5 0 correctly. 4 . 1 2 7 . 6 2 7.62

Don't forget to use a zero to show 2 0 9 that we are multiplying by 30 and not x 3 4 3. 8 3 6 2 7 6 0 7 1 0 6 7106
